Thunder Racing 215/230, .600/.578 CheaTR cam vs 231/234 .644/.598 TRak cam dyno After adding headers to my car, the CheaTR cam woke up, but just for grins, we slid in a larger cam that Thunder just came out with. Got 22 additional rwhp. The TRak (Thunder Racing ass kicker) cam is a very aggressive cam and is suited for those considering FMS F-13s, TSP 231/237s, and LG G5-X cams. The dyno was done on the same dyno exactly one day apart. All runs with cats and catback in place. All numbers SAE. Temps were around 99 degrees.

Ah nice, but 450rwhp seems slightly low with the FAST90 and AFR205s with a 230 duration cam. Maybe the cats, heat, and stock catback held it back a bit?
Either way, that's a nice pickup without losing much down low. And geez, .644" lift? Is that a lazy lobe with that sort of lift? And doesn't the 205s begin to stall around there? Just curious, because it's an interesting design that seems to mirror the CheaTRs driving characteristics, so somehow it works well.

What are the heads milled, compression, and did you have to fly cut the pistons on the intake? I've emailed Geoff and got a little info on the TRak, but that bitch is insane! 
I'm looking into the 230/236 TR cam for my LS6 heads, but I'll try anything!

Not slow on the intake!
Comp XE-R 232 lobe = 281 @ .006" (51 degrees from .006 to .050"), 153 degrees duration @ .200"
TRak cam 231 lobe = 281 @ .006 (50 degrees from .006 to .050"), 156 degrees duration @ .200.
That means the 231 TRak cam lobe has as much duration at .200" as a 234-236 XE-R lobe. Do the math from .006 to .050". 50 degrees is a faster ramp rate than 51 degrees of the XE-R. 156 degrees at .200" for the TRak cam is 3 degrees more than the XE-R even though the XE-R has a 1 degree advantage at .050". Slow ramps they are NOT!

Comp 921's set up by me. These spring's shimmed properly will easily handle those lobes. I have used these springs in the motor in Angie's car @ 8200 RPM with about the same lift.

Congrats on those numbers patrick. It was very nice meeting you Sat. Whenever you are back down we can line em up and see how my 408 does against that TRAK. J/J. Glad to see another satisfied Thunder customer. I wouldn't recommend another company in the world.
